Low levels of dopamine are tied to low motivation and depression. So, making sure you have enough — but not too much — is essential to living a happy, healthy, and functional life.
When dopamine makes its way to your brain, it binds to receptors in the brain that relay the message from one cell to another. This is how dopamine helps you feel pleasure like when you eat a good meal, take a brisk walk or run, attend a social engagement, give or receive praise or accomplish a goal.
